Most of the time, though, sitcoms are just the same old thing in different settings, cobbling ideas together from already successful shows during a very desperate board meeting. Sometimes they have an original idea, but it’s so outlandish that you can’t quite believe was pitched let alone accepted.

Bosom Buddies

Tom Hanks’ first screen appearance seems to be inspired by Some Like It Hot only more stupid and less funny. Some Like It Hot had to be in black and white for audiences to accept Tony Curtis and Jack Lemon as women, but the Bosom Buddies creators thought nah, it’ll be fine.

Tom and his chum find a cheap apartment to rent but oh, curses, it’s a hotel for women. Did…did those exist in the 1980s?

My Mother, The Car

Wanting to capitalise on the success of fantasy sitcoms like Mr Ed and Bewitched, with a little oedipal complex thrown in, the reviews for the sitcom in which a man’s dead mother is reincarnated as a 1928 Porter were so bad that it wasn’t picked up for a second series. I suggest you watch The Simpsons parody Lovematic Grandpa instead.

Diff’rent Strokes – The Paedophile Episode

I had to include this. Generally a regular, unfunny situational comedy, it took a dark turn when the writers decided to highlight the dangers of paedophiles.

While I think it was well meaning and may have done some real good, the story slips down a rabbit hole of inappropriate laugh tracks and wise cracks while the action onscreen grows ever more disturbing. If you’ve ever watched the Butter’s Very Own Episode of South Park you’ll know what I mean, only this was unintentional.

The Flying Nun

“There’s this nun, see.”

“OK?”

“And she can fly.”

“What? Why?”

“She weighs just 90 pounds and…and…when the wind is strong it catches that funny hat they wear, and off she goes!”

“Tere, your mother and I are very worried about you.”

Mr Smith

The orangutan from Any Which Way But Loose landed a speaking role in this short-running sitcom. Apparently transformed into a genius after drinking an “experimental mixture” (pesky stuff) he becomes a political adviser (?) while his assistant and secretary try to keep his ape identity a secret. Yes, I’m sure it was hilarious.

Bonus! full episode of Heil Honey, I’m Home

Hitler and Eva Braun live in an apartment next to a Jewish couple in this British parody of American 50s sitcoms which aired for a single episode. I suggest you read this review of the shockingly unfunny programme here. Don’t say I didn’t warn you.
